In the font identification function, serif typeface, bold Gothic typeface, and standard characters can be identified. Not only rough distinctions but also detailed distinctions such as "Heisei Mincho", "MS Mincho", and "TB Mincho" are possible.

An optional font dictionary creation tool is required. It can create font dictionaries from fonts installed on Windows, so it can also support fonts such as "KaiSho", "Kyokasho", "ReiSho", and "CAD font".
Currently, it takes about 0.2-0.3 seconds per font per paragraph. For 5 fonts, it takes 1-1.5 seconds, and for 10 fonts, it takes 2-3 seconds to identify.
The identification time does not increase even if the number of characters in a paragraph is several hundred because it extracts a maximum of 10 characters from the paragraph for font identification.
On the other hand, in paragraphs with less than 10 characters like personal names, the identification time becomes faster proportional to the length.
※The above speed is for Pentium-M 1.6GHz, and it is more than twice as fast for Core2 Duo.

It is also possible to standardize the height of fonts in millimeters, kyu units, or gou units.
Below is an example of processing to standardize the height of fonts.
